More Information

● The 85A series is much harder and generates finer particulates compared to A abrasive grains / WA abrasive grains. The life of grindstones will be extended and it also greatly reduces grinding resistance.
● Z300 abrasive grains are capable of maintaining their sharpness longer than 32A grindstones as they are fractured into an appropriate size for the grinding of difficult-to-machine SUS300 stainless steel. Also they are less prone to burn marks as they have less deposition on the work material and are capable of realizing a long dressing interval.
